How many passengers could the Blériot 75 'Mammoth' carry?

Short answer

Twenty-eight. The Type 75 Mammoth, a 28-seat transport aircraft prototype based on the earlier Type 74 bomber, was displayed at the Paris Air Show in December 1919. Despite the promising flight tests of its single example, no orders came in and the Type 75 proved a failure.

Twenty-eight seats

The Type 75 Mammoth was a prototype 28-seat transport aircraft, based on the earlier Type 74 bomber, and was displayed at the Paris Air Show in December 1919. This transport version had a longer rear fuselage and an enlarged vertical tail surface, but was otherwise similar to the Bl.74.

Derived from a bomber

After the crash of the Blériot Bl.73, Touillet developed the Bl.74, a heavy bomber and transport aircraft with a large lenticular double-bubble fuselage mounted on the lower wing. The Bl.74's flight trials at Villacoublay ended abruptly on 22 January 1920, when oscillations in the tail unit caused a structural failure and the fatal crash of its only prototype.
